Seems like the errata for RFC 7159 wasn't really solved in 8259, but another errata (with different wording) also exists for RFC 8259.

The footnote is referenced here:

cpython/Doc/library/json.rst

Lines 11 to 16 in 836fbda

`JSON (JavaScript Object Notation) <https://json.org>`_, specified by
:rfc:`7159` (which obsoletes :rfc:`4627`) and by
`ECMA-404 <https://ecma-international.org/publications-and-standards/standards/ecma-404/>`_,
is a lightweight data interchange format inspired by
`JavaScript <https://en.wikipedia.org/wiki/JavaScript>`_ object literal syntax
(although it is not a strict subset of JavaScript [#rfc-errata]_ ).

Is it really relevant for the Python documentation? Should we remove this sentence entirely?

JSON permits literal U+2028 (LINE SEPARATOR) and
U+2029 (PARAGRAPH SEPARATOR) characters in strings, whereas JavaScript
(as of ECMAScript Edition 5.1) does not.
